Vector Graphics Vector Graphics • Graphics that are based on mathematical formulas that define lines, shapes, and curves. • Are comprised of paths connected by anchor points. • Can be 2D or 3D. • Edited in draw programs. Examples Original Image Resized Image Shapes that make up the image. Uses of Vector Graphics • Graphics that will be scaled (or resized) • Architectural drawings, CAD programs, flow charts. • Logos that will be scaled (resized) with loss of quality. • Illustrations and clip art. • Graphics on websites. • Small file size allows for quick load times. • Fonts and specialized text effects Advantages of Vectors • Scalable – able to change size easily • Resolution Independent - Regardless of how much the image is enlarged or reduced, the image definition and quality remain the same. • Editability - since each vector is made up of separate and distinct objects, each can be edited independently at any time. • Small File Sizes - easily transferred over the Internet. Disadvantages of Vectors • Lower color quality than raster images. • They do not support as many colors. • Not good for photographic images. • Limited in the type of effects that can be applied. • Can be time consuming to create. Common Vector File Formats • AI – Adobe Illustrator • Native file format for Adobe Illustrator. • Industry standard used by developers of vector graphics. • Used to create, save, and archive original artwork. Common Vector File Formats • EPS – Encapsulated Postscript • Developed by Adobe but supported by most programs. • Graphics developers generally save a copy of the AI file in EPS format because it can be opened by computers running different operating systems. • Most common interchange format for the print industry due to its portability. • Meta Graphic – can contain both raster and vector data. • Shapes in vector graphics can be filled with textures and patterns that are raster graphics. 8 Common Vector File Formats • SVG – Scalable Vector Graphics • Standard format created by W3C. • Versatile, all-purpose vector format. • Works well with web page design. • WMF – Windows Metafile • Microsoft created format for raster and vector. • Common format for windows clipart. .

Understanding Image Formats and When to Use Them
Understanding Image Formats And When to Use Them Are you familiar with the extensions after your images? There are so many image formats that it’s so easy to get confused! File extensions like .jpeg, .bmp, .gif, and more can be seen after an image’s file name. Most of us disregard it, thinking there is no significance regarding these image formats. These are all different and not cross‐ compatible. These image formats have their own pros and cons. They were created for specific, yet different purposes. What’s the difference, and when is each format appropriate to use? Every graphic you see online is an image file. Most everything you see printed on paper, plastic or a t‐shirt came from an image file. These files come in a variety of formats, and each is optimized for a specific use. Using the right type for the right job means your design will come out picture perfect and just how you intended. The wrong format could mean a bad print or a poor web image, a giant download or a missing graphic in an email Most image files fit into one of two general categories—raster files and vector files—and each category has its own specific uses. This breakdown isn’t perfect. For example, certain formats can actually contain elements of both types. But this is a good place to start when thinking about which format to use for your projects. Raster Images Raster images are made up of a set grid of dots called pixels where each pixel is assigned a color.

Customizing Microsoft Clipart
Customizing Microsoft Clipart LBT140 with PowerPoint versions 2002 & 2003 As discussed in the lecture notes for this week’s module, appropriate imagery can have a significant, positive impact on a learner’s cognitive load as new information is being presented in a multimedia context. While using the Microsoft Office applications to create educational materials, we can easily find a vast assortment of clipart components ready to be integrated into any presentational format. Unfortunately, just as digital cable can offer its subscribers over 400 channels and still fail to air anything “worthy” of watching, Microsoft clipart can often miss the mark, if only by just a little bit. This leaves us with two options: 1. create our own clipart 2. customize what has already been created for us. This week we will choose option 2 and leave the custom creation of graphics for the next module. While the customization of clipart can be accomplished in Microsoft Word, Publisher or even Excel, we will be using PowerPoint to accomplish this task as it provides a little more freedom to move things around the way we will want them. Once you have started the PowerPoint application, you will need clear the default text boxes that appear on the initial slide. Open the Edit menu and choose Select All. This will select the current slide’s title and subtitle text boxes. Next press the Delete key on your keyboard. Now we will need some clipart on which to practice the customization process. From within the Insert menu select Picture and then select Clip Art from the secondary menu.

FILE FORMATS Darry D
WordPerfect FILE FORMATS Darry D In WordPerfect, when you select File > Open, you are taken to “My Documents.” However, that does not mean that you can open all the files that are stored there. Here are the programs that can open a file, based upon its file extension. A file extension is a string of characters beginning with a period and followed by one to three letters; the optional second part of a PC computer filename; “most applications provide extensions for the files they create”; for example, WordPerfect uses the file extension “wpd”. o .cgm — CGM (Computer Graphics Metafile) was a once-standard for- mat for interchanging graphics images. CGM stores images primarily in vector graphics, but also provides a raster format. Earlier GDM and VDM formats have been merged into CGM. There are many non-standard varieties of CGM in use. Usually found in the “My Pictures” folder of “My Documents” or some other graphics folder (such as “Art”), it can be inserted into WordPerfect 9 using Insert > Graphics > From File (from the MenuBar). o .cvs — comma-delimited file (a database with items separated by commas); this one can be opened only by importing it into the Outlook Express Address Book. o .doc — Created with MS Word; WordPerfect can open it. o .eml — Email created by Outlook Express or Outlook either of which can open it. Http://DarryD.com (5 November 2020) Page 1 of 4 WORDPERFECT 5 NOVEMBER 2020 o .htm —. It is the file extension of HTML, created by programs like Microsoft FrontPage and others, including WordPerfect.

About Graphics/Digital Images
About Graphics/Digital Images Digital images are found in lots of file formats (types) that are used for various reasons. I liken the file formats to flavors of ice-cream, which you might or might not choose to consume on any given day. One day chocolate is more important than mint; another day you might use vanilla, and on another day you might decide to combine more than one flavor in the same bowl. Likewise, you might choose one type of graphic file for a particular project, but it might be completely inappropriate for another project. What works well for display purposes (keeping it on the computer, or for publication to the internet) might not print well. Something that prints well might be too big a file to post to the internet, or may make your program run too slowly. Also, some authoring programs (like Boardmaker or Classroom Suite) might be written to only understand certain types of image files. Some file types are more common than others, and are more likely to be recognized by the “parent” program (the one you use to display, edit or print your image). Whatever type you pick ultimately depends on how you plan to use the image. The more technical definitions provided below are taken from the glossary found at http://www.photoshopelementsuser.com/glossary.php?letter=B The additional comments I have added, and hopefully let you know why you would care about any of this, anyway. The two biggest types of images I describe here fall loosely into two categories: vector images and bitmap images.

Macintosh Desktop Pictures Control Panel a Dialog Box Will Open Which Shows the Contents of the Sample Desktop Pictures Folder
Macintosh Desktop Pictures by Cindy O'Hora One of the features I enjoy in my Mac is the desktop pattern. I changed my Desktop's appearance on a monthly basis. I collected sets from the Internet. You cannot imagine how thrilled I was when they added the Desktop Picture feature in OS 8. Desktop in 8.5 Where Desktop Pattern allowed you to apply art to your desktop, Desktop Pictures allows you to use photos. Beautiful professional photos, homey family photos, thematically appropriate photos, you have lots of options. One of my Mac friends bought a clip art collection. He received a CD with professional photographs on it. At the time it was not clear to him what he could do with them. As soon as he upgraded to Mac OS8, their usefulness became clear. 1. Go Apple Menu Items...Control Panels.... Desktop Pictures. You are presented with two options. When you click on the pattern button, you'll be offered a wealth of interesting or plain patterns. 2. Click on Picture to set the Desktop Picture. If you have been using only pattern, begin by hitting the Select Picture button. ©1999 Cindy O'Hora All Rights Reserved http://homepage.mac.com/cohora/computer/desktoppicts.pdf Macintosh Desktop Pictures Control Panel A dialog box will open which shows the contents of the Sample Desktop Pictures folder. Apple provides several pictures to get you started. 1. Click on one of them and see the photo in the preview box. 2. Make your choice and click Open. 3. You will return to the Control Panel.
